Product modeling and data exchange has been recognized as one of the sky issues of implementing a product overall lifecycle management (PLM) system. In this paper, a product integrated models during the whole phases of lifecycle is proposed first. Based on the integrated models, a multidisciplinary collaborative design method over Internet is discussed. STEP/EXPRESS, UML and XML are employed during the product modeling process. And a mapping relationship schema among different data schema is presented for product data exchange. Finally, a PLM prototype system is implemented based on J2EE, the proposed product integrated models. And primary technical ideas are validated.
